Enable DTS 3D Stereo sound on all LG V30 variants [Root]
There are a number of cases where an OEM is using hardware in their device but then goes in and uses the software to limit its capabilities. The enthusiast community here at XDA is well known for bypassing these restrictions, but then there’s a case like LG. They have added (and even mentioned the addition of a feature in an OTA changelog) but ended up messing up the initial implementation of a feature. This seems to have happened with the LG V30 variants and their DTS 3D Stereo sound.
